The edge guide is two-sided. One side, pictured above left, has a straight edge and the other side, pictured above right, has a concave edge.

If you want a dead flat surface on your wheel, use the straight edge against your tool rest.

If you want a Spherical- Crowned surface on your wheel, use the concave side against our Crowning Tool Rest.

There are advantages to each, depending on the application.

Geiger's Wheel Crowning System dresses wheels in two radial planes creating a complex curve. This results in a spherically surfaced wheel .

Sharpening on a spherical surface reduces heat by minimizing friction. This is critical when sharpening plane irons, chisels, etc.

In addition to making the surface of grinding wheel flat or crowned here are some of the additional benefits of the TND Grand Slam and Crowning System:

in the grinder and in tools applied to the surfaces of the wheels.

Performs wheel balancing by eliminating eccentricities in the circumference of grinding wheels- not by counterbalancing.

It very effectively smooths the aggregate across the face of the wheel which significantly improves the bevels and sharpened edged of tools.

Reduces heat by de-glazing the wheels.

Improves sharpening by exposing fresh, sharper aggregate.

The diamond is Micro-adjustable- minimizing the amount of material removed which extends the life of your wheels.

The TND Grand Slam has significant mass and has a fulcrum point very close to the surface of the wheel and does not vibrate when being used.

Easy to use!

Supplied with a long-lasting 1/2 ct. diamond.

Spending money on a wheel balancing system is unnecessary in almost all cases!

Balancing kits only treat the symptom: (grinder vibration) and do not correct the source of the problem (out of round wheels). If a grinding wheel is out of round, your tools will still bounce on the surface which adversely affects sharpening. Every instruction manual we've studied that comes with a balancing system recommends truing the wheels too. We suggest truing the wheels first and then test the grinder and decide if you need to go further.

Testimonial:

"Paired with Don's grinder tune up kit, my $100 grinder suits my needs just as well as one costing almost ten times that much. I'm also glad I heeded his advice to hold off on buying a wheel balancing product, for which I haven't since seen a need. Don's offerings are the right fit for me because I believe in not only investing in quality tools, but also allocating my budget wisely."

Try a TND Grand Slam first to see if it solves your problems before going to the expense of purchasing a balancing system. We believe it will work.

Tru N Dress users have been very successful at correcting vibration problems without purchasing a wheel balancing kit. Besides- you'll still need a TND Grand Slam even if you decide you need a balancing system.

The TND Grand Slam works on tools rests from 1" to 3-3/16" (front to back).

The TND Grand Slam can be used on most original equipment and after market tool rests.

The TND Grand Slam, pictured right works perfectly on a One Way Wolverine 3" X 5" platform tool rest, without modification.

The diamond can actually be retracted all the way into the body to minimize the fulcrum thus minimizing vibration.

The TND Grand Slam is supplied with a long-lasting 1/2 ct. diamond for use on wheels up to 8" diameter.

The 1/2 ct. diamond is permanently mounted to a 1/2" threaded steel shaft. The diamond is expected to be long lasting and we see very few replacements necessary. The replacement shaft/diamond and a new knob.

If you are using a hand controlled wheel dresser, such at a T shaped one or similar, it's very likely you are unable to make the wheels perfectly concentric to the axle. Also, the bevels of your tools will have a rough appearance and the edges of the tools are not as sharp as they could be. Multi-diamond dressers dig furrows in the surfaces of the wheels making the results on your tools rougher.The TND Grand Slam will solve these problems because it has a controlled depth of cut and very effectively smooths the aggregate across the face of the wheel.

Improve your sharpening today with a new TND Grand Slam! We suggest using it every day before sharpening your tools. Hundreds of our customer's have reported they think this is the best wheel dresser available today. Most of our customers abandoned other systems in favor of the TND Grand Slam.

To effectively tune up a grinder: It is helpful to first replace the plastic bushings, as are supplied with some wheels, with steel bushings. A steel bushing will provide a solid mounting that is more concentric and perpendicular to the axle. It is also advisable to correct the side-to-side wheel wobble using paper shims.

A complete description of the recommended procedures to tune up a grinder can be viewed here.

We offer precision machined steel wheel bushings in three sizes:

5/8" i.d. X 1" o.d. X 1" long (fits most 8" grinders)

3/4" i.d. X 1" o.d. X 1" long (fits 8" Baldor grinders)

1/2" i.d. X 1" o.d. x 3/4" long

(fits 6" Baldor grinders)

These are very precisely made headless press-fit drill bushings and are machined to very exacting specifications.
